Sector 8-1

Going-on Activities

  • It has been decided to repair the flexibles in the DFBAs of Sector 8-1 before the global leak tests, allocated dates are:
    • DFBAP repair: Wk 44
    • DFBAA repair: Wk 45

  • SSS Interconnection

  • Inner Triplets:
    • Left 1: closed, being leak tested
    • Right 8: closed, being leak tested

From the Pressure Tests to the Cooldown - Sector 8-1 - October 19, 2007

Sector 8-1

Going-on Activities

  • SSS Replacement

  • Inner Triplets:
    • Left 1: closed, being leak tested
    • Right 8: closed, being leak tested

  • Electrical non-conformities on instrumentation cables of the power converters will be closed by the end of the week.

  • The procedure for cleaning the DFBXH is currently being completed. In principle, the instrumentation wont have to be removed.

Planned activities

  • PIC-PC interface test - Wk 43
  • Room temperature vacuum and collimator works (wks 43-46), bake-out (wks 47 -48)
  • ATLAS-RP cable installation - Wks 48-49
  • TS/EL:
    • DFBXH Ineo cabling - To be done on Monday 22.
    • Installation of the removed water-cooled cable and RQ6 - Flohe Wk 44 - 45 Once the cleaning is completed.
    • NC DFBXH: The water cooled cable associated to the current lead #3 cannot be fixed to the lead on the left side. There is a mechanical interference between the water tube on the lug and a connector necessary for the routing of the protection signal from the intrumentation port. The connector cannot be moved to another position, it is therefore proposed to fix the water cooled cable on the right side of the current lead lug.
  • ElQA
    • TP4-A: Inner triplet L1 - as soon as possible since it will be the first time they are performed
    • TP4-A: Inner triplet R8 - not before the DFBX is repaired
  • Alarm test in the whole sector will be carried out on Wednesday 24.

General

  • Cooling water shut-down - Wks 42-44 - All the cryogeninc activities will be stopped.
  • A latest date for taking a decission about repairing or not the DFBAs has to be set for not jeopardizing the starting date of the flushing

From Pressure Tests to Cooldown - Point 8 - Monday 09.10.2007

Sector 8-1

  • Inner Triplets
    • Right 8: the leak has been located in line C', precisely on a weld in the middle of the flexible. It is currently being replaced by the US collaborators. Once it is corrected and the works in the SSS completed, the inner triplet will be pressurised again for testing. It should be sufficient for this test to have the C' line in the SSS welded, however it is not sure that only one line can be pressurised without affecting the other lines, hence most likely the test will be carried out at the end of the SSS works (wk 47).
    • Left 1: inner triplet closed and being leak-tested.
  • SSS Q17R8
    • The replacement of the SSS started this week and will last till wk 46.
    • Local electrical tests will progress in parallel with the assembly of the SSS.
  • MB1158
    • The diode has been cleaned up. A continuity test will be done before closure beginning of next week. The final validation cannot be done before the TP4-A before the flushing.
  • DFBAs repairs
    • A latest date for taking a decission about repairing or not the DFBAs has to be set for not jeopardizing the starting date of the flushing.
    • Paolo reminds that the time used for reparing the DFBAs will be different for each sector due to the different configurations.
  • ElQA
    • TP4-A is planned for week 47, just before the flushing.
    • Low voltage continuity tests of the dipole lines will be carried ut during the SSS replacement between the DFBAA and C18R8
    • The non-conformities being corrected by INEO this week will be re-checked once they are closed.
  • AUG Test
    • The yearly AUG test for the whole Point 8 is planned for October 19. HCC will study how can we get the maximum profit from it.
  • A4L1
    • Vacuum mechanical works will start on week 43 and will last till week 47.
    • Collimator to be installed week 44.
    • Neg-activation weeks 48 and 49 (overlaps with one week of flushing)
  • LHCb Compensator Magnet Tests
    • The three compensator magnets will be on today and tomorrow. No interference with other activities.
  • Cryogenics
    • Nothing pressurized in the cold circuits.
    • Warm helium line a few mbars above atm pressure
    • Installation of the instrumentation rods in the DFBs of Right 8 will be done tomorrow Wednesday
